补充资料:甲黄隆
分子式:C14H15N5O6S
分子量:381.37
CAS号:74223-64-6

性质:外观为白色结晶固体。熔点163-166℃。水中溶解度因pH值而异。pH 溶解度(mg/L)4.56 2705.42 17506.11 9500在土壤中,因水解和微生物降解而破坏,半衰期为7-3d。

制备方法:合成步骤如下。1.2-磺酰胺基苯甲酸甲酯的制备 将30g糖精和250ml甲醇加入反应瓶,在0℃以下通入HCl气体。反应毕,蒸除过量的甲醇。在残留物中加入乙酸乙酯,滤除未反应的糖精。蒸除乙酸乙酯,残留物经重结晶而得。熔点122-124℃。2.2-(磺酰基异氰酸酯)-苯甲酸甲酯的制备 将2-磺酰基苯甲酸甲酯13.4g,二甲苯100ml和催化量的异氰酸正丁酯,以及少许1,4-二氮杂二环[2,2,2]辛烷,加入反应瓶中,搅拌,于120℃时通入光气。反应结束,升温到136℃,然后冷却至室温。过滤,滤液脱溶后减压蒸馏,收集140-150℃(0.267kPa)馏分而得。3.甲黄隆的制备 将2-氨基-4-甲氧基-6-甲基均三嗪1.4g、二氯甲烷30ml和2-磺酰基异氰酸酯苯甲酸甲酯2.4g,加入反应瓶,于室温搅拌反应16h。过滤,滤液除去溶剂后,残留物用氯丁烷磨碎得白色晶体,熔点158-164℃。配制成20%乳油,5%颗粒剂。
